1 container (8 oz) green onion cream cheese: Infuses a subtle tang and creaminess while boosting the flavor with green onion.
¼ cup olive oil: Brings richness to the sauce and keeps everything moist.
½ cup chicken broth: Adds savory depth and helps make the sauce velvety and smooth.
1 large package of sliced mushrooms: A savory, earthy element that pairs wonderfully with both chicken and spinach.
1 small bag of fresh baby spinach: Provides color, nutrients, and a gorgeous freshness that lightens every bite.

How to Make Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe

Step 1: Preheat the Oven

Start by setting your oven to 375°F (190°C). This ensures the perfect temperature right from the get-go, so your Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe bakes up beautifully and everything cooks evenly.

Step 2: Layer the Chicken

Place the thin-sliced chicken breasts in a single snug layer inside a 13×9-inch baking dish. Season generously with salt, pepper, and that signature dash of Weber Herb and Garlic Seasoning. This quick seasoning step locks in moisture and elevates the chicken with herby, garlicky flavor.

Step 3: Sauté the Mushrooms

In a skillet over medium heat, drizzle a splash of olive oil and sauté your sliced mushrooms until they’re soft and just turning golden. Mushrooms release their earthy aroma as they cook, making your kitchen smell incredible. Spread the sautéed mushrooms directly on top of the chicken, followed by a layer of fresh baby spinach for a pop of color and goodness.

Step 4: Prepare the Creamy Sauce

In a medium mixing bowl, combine the green onion cream cheese, chicken broth, and olive oil. Whisk everything together until you have a silky, pourable sauce. Drizzle this luscious mixture over the mushrooms, spinach, and chicken, ensuring an even coating for maximum creaminess in every single bite.

Step 5: Cover and Bake

Loosely cover the baking dish with foil (no need to seal it tight!). Slide it into your preheated oven and bake for 20 minutes. Covering helps steam the chicken so it stays juicy and tender while allowing the flavors to mingle and build depth.

Step 6: Uncover and Continue Baking

After 20 minutes, remove the foil to expose the top of the dish. Bake for another 20 minutes, letting the flavors develop further, the sauce thicken, and the mushrooms brown just a bit more for maximum savory appeal.

Step 7: Add the Mozzarella and Finish Baking

Sprinkle your shredded mozzarella in an even layer across the top. Return the dish to the oven for 5-10 minutes, watching closely as the cheese melts, bubbles, and turns irresistibly golden. Your kitchen will be filled with the mouthwatering aroma of the finished Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe.

Step 8: Serve and Enjoy!

Dish it up hot—directly from the oven to eager plates! That creamy sauce, the cheese pull, and the perfectly cooked chicken with veggies make every bite pure comfort.

How to Serve Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe

Garnishes

For a final bright touch, sprinkle fresh chopped parsley or snipped chives over the top. A few twists of cracked black pepper never hurt, and a handful of microgreens can add both color and a peppery kick to each serving.

Side Dishes

This dish plays beautifully with simple sides like a crisp green salad, roasted cauliflower, or steamed asparagus. Keeping it low-carb? Try cauliflower mash to soak up that irresistible sauce, or roasted Brussels sprouts for a nutty, caramelized complement.

Creative Ways to Present

Serve the Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe in individual ramekins for a dinner party twist. Or, spoon it onto zucchini noodles or cauliflower rice for extra veggies and a fun plating flair. If you want to wow your guests, top each portion with a tiny drizzle of good olive oil and a sprinkle of lemon zest just before serving.

Make Ahead and Storage

Storing Leftovers

Let the dish cool to room temperature, then transfer leftovers to an airtight container and refrigerate. Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe stays fresh and tasty for 3-4 days, making it a fantastic meal-prep option for the week ahead.

Freezing

To freeze, portion the cooled casserole into freezer-safe containers (or wrap in foil and place in freezer bags). It keeps well for up to two months. For best results, avoid freezing right after baking; let it fully chill in the fridge first, so the sauce stays creamy.

Reheating

To reheat, place portions in a covered baking dish and warm at 350°F (175°C) until hot and bubbly—usually about 15-20 minutes. For a quick lunch, you can also use a microwave, heating in 1-minute bursts and stirring in between. A little fresh mozzarella on top as it reheats will revive that golden, melty topper!

FAQs

Can I use boneless chicken thighs instead of chicken breasts?

Absolutely! Boneless thighs add extra juiciness and a richer flavor. Just be sure to trim excess fat, and adjust baking time if needed since they can be a bit thicker than thin-sliced breasts.

Is it possible to make this recipe dairy-free?

It sure is. Try using a plant-based cream “cheese” (like almond or cashew cream cheese), a dairy-free cheese shreds alternative, and swap the chicken broth for a low-sodium veggie broth if desired. The creaminess and flavor is still spot on!

Do I need to cook the spinach ahead of time?

Nope! Just layer the fresh baby spinach right into the baking dish. The oven will wilt it perfectly as the casserole bakes, preserving its bright color and nutrients.

What’s a good substitute for Weber Herb and Garlic Seasoning?

If you can’t find this blend, use an Italian herb mix with an extra pinch of garlic powder. You’ll achieve similar savory herb and garlic notes that make the Chicken, Spinach, and Mushroom Low-Carb Oven Dish Recipe so aromatic.

Can I assemble the dish ahead and bake it later?

Yes! Prep everything in the baking dish and cover tightly before refrigerating for up to 24 hours. When ready to bake, let it come up to room temp while the oven preheats, then follow the same baking times as in the recipe.
